DETAILED DESCRIPTION

A method and system of indoor navigation are described for a user using a mobile electronic device. The method and system use other user's mobile electronic devices as beacons to determine the user's position. Calendar or scheduling data is used to map the other users to known locations in an indoor establishment from which the user's position can be determined.

The method scans for other user's mobile electronic devices nearby and uses them as dynamic beacons assigning positions on a site map using information about the expected temporal location of a device on the map.

This method is applicable to locations in an establishment site. An establishment site may be a large corporate office, a retail park, an educational environment, or other establishment in which there are registered users whose details are provided on a database including scheduling information for the users. In a corporate environment, employees may be registered in a database including scheduling capabilities for meetings and other events. In a retail environment such as a shopping mall, shop employees and other staff may be registered in a database with their working shift schedules and locations. Similarly, students in a university campus may be registered on a database with their lectures and tutorials and locations.

The method provides crowd-sourced location information that may be used to aid an Indoor Positioning System (IPS) by using presumed locations of other devices in a given establishment or area. An application needing to use an IPS may add the described functionality to the software stack in the device that wants to be positioned.

The method may use a Lightweight Directory Access Protocol (LDAP) for accessing distributed directory information services over an Internet Protocol (IP) network for an enterprise or organization.

The advantage of the described method and system is that there is no need to deploy additional hardware to the establishment, it is not dependent on an existing wireless infrastructure, and it does not require calibration.

Referring to FIGS. 1A and 1B, schematic diagrams show an example embodiment of an establishment site 100 including multiple rooms 110, 120, 130, 140, 150 and a corridor 160.

A first user 101A has a first user mobile electronic device 101 and the first user 101A wishes to establish her location in the establishment. She may have a meeting in a room 110 and may be unsure of the room's location relative to her current position.

Second users 111A-114A, 121A-123A, 131A, 141A, 151A may be located in nearby rooms 110, 120, 130, 140, 150. These may be, for example, meeting rooms or open-plan workspaces 110, 120 in which multiple second users 111A-114A, 121A-123A are present, or individual workspaces 130, 140, 150 where one or two second user are present 131A, 141A, 151A.

As described further below, the first user 101A may use her mobile electronic device 101 to scan the surrounding area within a radius of her current location. The first user 101 who wishes to use the navigation functionality must access or download software onto her mobile electronic device 101 with permissions to scan for other user devices.

The scan may obtain a list of nearby second user mobile electronic devices with an identifier such as a media access control (MAC) address. The scan may be by a wireless technology standard such as WiFi or Bluetooth®.

The first user mobile electronic device 101 may access one or more resources of users that identifies second users of the second mobile electronic devices and provides a schedule of the expected locations of the second users in the establishment site. This may be carried out via a server, such as a central server of the establishment or a cloud server, or this may be carried out on the first user mobile electronic device 101 via scheduling functionality. The individuals, their schedule data, and the devices registered to the individuals may be provided by multiple databases and scheduling systems that already exist for users within an establishment.

As illustrated in FIG. 1B, the room locations of the second users may be obtained from the second users schedules and may be referenced to a site map of the establishment site. A geographical referencing method such as trilateration or triangulation may be used to determine the first user's location from distances 115, 125, 135, 145, 155 from each room 110, 120, 130, 140, 150 in which scanned second users are located.

Referring to FIG. 2 , a swim-lane flow diagram 200 shows an example embodiment of a method at a mobile electronic device 101 of a first user and a server 210. Some of the method steps shown on the server 210 may be carried out on a mobile electronic device 101.

The mobile electronic device 101 may scan 201 an area around the current location of the first user to identify a set of second mobile electronic devices. The method at the mobile electronic device 101 may reference 202 one or more resources using the set of second mobile electronic device identifiers.

The referencing 202 by the mobile electronic device 101 may access a database via a server 210 providing reference functionality. The server 210 may identify 211 a set of second users of the identified set of second mobile electronic devices from a register of users. The method may analyze 212 schedules of the set of second users to identify expected current locations of the second users and may identify 213 expected current locations of the set of second users. This may also be carried out via the server 210 or via scheduling functionality of the mobile electronic device 110.

Rules and statistics may be applied to identify an expected current location of a user. For example, there may be probabilities assigned to meeting participants to determine their likelihood of being physically at a scheduled location. Different factors may affect the probability, including whether the user is the room booker or an attendant. The booker may be given a slightly greater weight than the other attendants as those who book room are more likely to be physically present in a room.

A scheduling resource of a Lightweight Directory Access Protocol (LDAP) may be used for accessing distributed directory information services over an Internet Protocol (IP) network. The directory service may provide an organized set of records, such as an enterprise contacts directory. The LDAP may contain information about users' default office and scheduled meetings. This may be combined with information about the users' devices such as their MAC addresses.

Information about default site locations may also be used. If, for example, a user is not in a meeting, then he is expected to be in his default office address.

There are many other factors that can influence the probability of an individual being at a specific location.

The method at the server 210 may reference 214 a site map and may identify 215 a current location of the first user relative to the expected current locations of at least some of the second users. This may use a geographical referencing method such as trilateration or triangulation from known locations of the second users.

The server 210 may provide this information to the first user mobile electronic device 101 that receives 203 notification of the positions of the current location in the establishment site and may also receive 204 navigation instructions to navigate from the current location to a target location in the establishment site.

The LDAP may be used to initiate the described navigation method and may offer another source of verification once the use of the method is prominent.

The LDAP may be used to detect where the user navigating the site is. For example, if a first user Fred is walking around A block and detects a colleague Dan's signal, Fred may check with the LDAP where he is supposed to be right now. If the answer is A121, which is Dan's default office, then it adds to the probability that Fred is in A block. If the answer is D121, a meeting room with 12 people, then it adds to the probability that Fred is in D block. The D block location may be tested by checking if the devices of the other meeting attendees are also detected. The method may also create a probability score of “did Dan actually move from his desk to the meeting room for this meeting”, to determine the likelihood that this is the location of Dan's device.

This may be carried out for tens of second users' devices for a first user, and a confidence score may be obtained of where the first user is. In the long term, the LDAP will not contribute as much weight to the confidence score as other users using the described installed device software. As more users install the device software, the method may detect the location directly from calendar or user data on the devices, without having to go through the LDAP and hardware MAC address lists in the backend.

Referring to FIG. 3 , a block diagram shows an example embodiment of a mobile electronic device 101 and a server 210 providing the described functionality.

The mobile electronic device 101 may be any form of identifiable electronic device that may be carried around by a user. This may be a smart phone, a tablet, a laptop computer, etc. The mobile electronic device 101 may include at least one processor 301, a hardware module, or a circuit for executing the functions of the described components which may be software units executing on the at least one processor. Memory 302 may be configured to provide computer instructions 303 to the at least one processor 301 to carry out the functionality of the components.

The mobile electronic device 101 may include a client navigation system 320 including a scanning component 321 for scanning an area around a current location of the first user to identify a set of second mobile electronic devices. The scanning component 321 may use a wireless technology standard scan and identifies media access control (MAC) addresses of other users' mobile electronic devices.

The client navigation system 320 may include a referencing component 322 for referencing one or more resources 340 via a server navigation system 330 for: identifying a set of second users for the set of second mobile electronic devices; analyzing schedules of the set of second users to identify expected current locations of each of the set of second users in an establishment site; and identifying the current location of the first user relative to the expected current locations of at least some of the set of second users by referencing a map of the establishment site. In one embodiment, the resources 340 may include an LDAP system.

The client navigation system 320 may also include a position component 323 for receiving notification of a position of the current location in the establishment site and a navigation component 324 for receiving navigation instructions from the current location to a target location in the establishment site.

The server 210 may include at least one processor 311, a hardware module, or a circuit for executing the functions of the described components which may be software units executing on the at least one processor. Multiple processors running parallel processing threads may be provided enabling parallel processing of some or all of the functions of the components. Memory 312 may be configured to provide computer instructions 313 to the at least one processor 311 to carry out the functionality of the components.

A server navigation system 330 may be provided at the server 210 in communication with the client navigation systems 320 of multiple users.

The server navigation system 330 may include a user identifying component 331 for identifying a set of second users for the set of second mobile electronic devices received from the client navigation system 320. This may reference a resource 340 mapping users to user devices.

The server navigation system 330 may include a schedule referencing component 332 for analyzing schedules of the set of second users provided via the resources 340 and an expected location component 333 for identifying expected current locations of each of the set of second users in an establishment site. The schedule referencing component 332 may reference the resources 340 that include schedules of registered users including a location directory of events with participants within the establishment site. The resources 340 may include LDAP resources.

The schedule referencing component 332 may include applying a default location for a second user if the second user has no scheduled event and applying probability rules to determine the probability of a second user being at a scheduled event.

The server navigation system 330 may include a current location component 335 for identifying the current location of the first user relative to the expected current locations of at least some of the set of second users by using a map referencing component 334 to reference a map 350 of the establishment site.

An example scenario is now described in a corporate site with access to a database of meetings happening in the site, the attendees, and the devices registered to those attendees. The method scans for nearby Bluetooth® and WiFi signals of other employees. If the method detects a set of devices of other employees, who are expected to be meeting in a specific location at this time, then the device may infer that it is near that location. With this information extrapolated to several events happening on site, the device may position itself.

A user of the method wants to know what room area he is in, in order to inform a colleague. The method scans the location and detects several other devices in the vicinity (e.g. smartphones, laptops). The method records the MAC addresses of the devices to identify them. The method retrieves the owner information of those other devices and the schedule information of these owners, giving an expected location.

The method identifies the nearby devices belong to three people who are currently scheduled to be in room G201. It is therefore highly likely that the location of these devices is room G201.

The method may verify that this MAC address is where it is supposed to be by cross checking with other MAC addresses it has detected. If it detects the MAC address of three out of five participants of a specific meeting, then it will be more confident that they are actually meeting together in the same room than if it were to only detect one out of five participants.

The more devices in the vicinity with a presumed location attached (desk number, cashier location, meeting room, etc.) the more confidence the method may have on it's determined location.

Using multiple locations of owners of the devices, the location of the user can be trilaterated, triangulated or calculated by another geometric means and the user's location is pinpointed on the map of the site.

FIG. 4 shows a block diagram of a mobile electronic device 101 that may be used in embodiments of the disclosure. The mobile electronic device 101 may be a smart phone, a satellite phone, a tablet or a mobile computing device.

The mobile electronic device 101 may include a processor 405 (e.g., a microprocessor) for processing the functions of the mobile electronic device 101 and a display 420 to allow a user to see the phone numbers and other information and messages. The mobile electronic device 101 may further include an input element 425 to allow a user to input information into the device (e.g., input buttons, touch screen, etc.), a speaker 430 to allow the user to hear voice communication, music, etc., and a microphone 435 to allow the user to transmit his or her voice through the mobile electronic device 101.

The processor 410 of the mobile electronic device 101 may connect to a memory 415. The memory 415 may be in the form of a computer-readable medium that stores data and, optionally, computer-executable instructions.

The mobile electronic device 101 may also include a communication element 440 for connection to communication channels (e.g., a cellular telephone network, data transmission network, Wi-Fi® network, satellite-phone network, Internet network, Satellite Internet Network, etc.). The communication element 440 may include an associated wireless transfer element, such as an antenna.

The communication element 440 may include a subscriber identity module (SIM) in the form of an integrated circuit that stores an international mobile subscriber identity and the related key used to identify and authenticate a subscriber using the mobile electronic device 101. One or more subscriber identity modules may be removable from the mobile electronic device 101 or embedded in the mobile electronic device 101.

The mobile electronic device 101 may further include a contactless element 450, which is typically implemented in the form of a semiconductor chip (or other data storage element) with an associated wireless transfer element, such as an antenna. The contactless element 450 may be associated with (e.g., embedded within) the mobile electronic device 101 and data or control instructions transmitted via a cellular network may be applied to the contactless element 450 by means of a contactless element interface (not shown). The contactless element interface may function to permit the exchange of data and/or control instructions between mobile electronic device circuitry (and hence the cellular network) and the contactless element 450.

The contactless element 450 may be capable of transferring and receiving data using a near field communications (NFC) capability (or near field communications medium) typically in accordance with a standardized protocol or data transfer mechanism (e.g., ISO 14443/NFC). Near field communications capability is a short-range communications capability, such as radio-frequency identification (RFID), Bluetooth®, infra-red, or other data transfer capability that can be used to exchange data between the mobile electronic device 101 and an interrogation device. Thus, the mobile electronic device 101 may be capable of communicating and transferring data and/or control instructions via both a cellular network and near field communications capability.

In this regard, each block in the flowchart or block diagrams may represent a module, segment, or portion of instructions, which comprises one or more executable instructions for implementing the specified logical function(s). In some alternative implementations, the functions noted in the blocks may occur out of the order noted in the Figures. For example, two blocks shown in succession may, in fact, be executed substantially concurrently, or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved. It will also be noted that each block of the block diagrams and/or flowchart illustration, and combinations of blocks in the block diagrams and/or flowchart illustration, can be implemented by special purpose hardware-based systems that perform the specified functions or acts or carry out combinations of special purpose hardware and computer instructions.

It is to be understood that although this disclosure includes a detailed description on cloud computing, implementation of the teachings recited herein are not limited to a cloud computing environment. Rather, embodiments of the present invention are capable of being implemented in conjunction with any other type of computing environment now known or later developed.

Cloud computing is a model of service delivery for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, network bandwidth, servers, processing, memory, storage, applications, virtual machines, and services) that can be rapidly provisioned and released with minimal management effort or interaction with a provider of the service. This cloud model may include at least five characteristics, at least three service models, and at least four deployment models.

Characteristics are as follows:

On-demand self-service: a cloud consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with the service's provider.

Broad network access: capabilities are available over a network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs).

Resource pooling: the provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to demand There is a sense of location independence in that the consumer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter).

Rapid elasticity: capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time.

Measured service: cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported, providing transparency for both the provider and consumer of the utilized service.

Service Models are as follows:

Software as a Service (SaaS): the capability provided to the consumer is to use the provider's applications running on a cloud infrastructure. The applications are accessible from various client devices through a thin client interface such as a web browser (e.g., web-based e-mail). The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.

Platform as a Service (PaaS): the capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including networks, servers, operating systems, or storage, but has control over the deployed applications and possibly application hosting environment configurations.

Infrastructure as a Service (IaaS): the capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications, and possibly limited control of select networking components (e.g., host firewalls).

Deployment Models are as follows:

Private cloud: the cloud infrastructure is operated solely for an organization. It may be managed by the organization or a third party and may exist on-premises or off-premises.

Community cloud: the cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be managed by the organizations or a third party and may exist on-premises or off-premises.

Public cloud: the cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services.

Hybrid cloud: the cloud infrastructure is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load-balancing between clouds).

A cloud computing environment is service oriented with a focus on statelessness, low coupling, modularity, and semantic interoperability. At the heart of cloud computing is an infrastructure that includes a network of interconnected nodes.

Referring now to FIG. 6 , illustrative cloud computing environment 50 is depicted.
